"Because if I should have waited for Juric and he says in the weekend 'I'm not fit', then I have no chance to get a new player to see him and then a new player has no chance to show what he can (do) to me."

With a lack of goals a major problem in Australia's qualifying campaign for Russia, Andrew Nabbout and Nikita Rukavytsya will also be hoping to get a chance against the Czechs to press their claims for the striker's role.

Van Marwijk must also give some consideration to the lack of playing time Tim Cahill has had this season.

The 38-year-old is by far Australia's most potent international striker with 50 goals in 105 games, while Juric is a poor second among the forwards in the squad with eight in 34.

Australia will also play a final warm-up against Hungary on June 10 before heading to Russia, where they face France, Denmark and Peru in the opening round.

"I hope I can see a lot of things that we trained until now," van Marwijk said of the friendly against the Czechs.

"It's always better when you get a result. The development is going quicker.

"When you lose you have to work harder, but I prefer to lose both games 5-0 and win the game against France. We have to be ready against France. But I don't like to lose. Never."
